A new Heterocarpus (Crustacea, Decapoda, Pandalidae) from South-West Pacific

A new species, Heterocarpus intermedius, confused until now with H. woodmasoni Alcock, 1901, is described after specimens caught off the east coast of Australia, New Caledonia, the Loyalty and Chesterfield islands, and the Combe and Tuscarora banks. It can be separated mainly by the fact that it has no postrostral crest and only two pairs of dorsolateral spines on the telson. An addition to the identification key of the Heterocarpus species published by Crosnier (1988) is proposed.
